We’ve been making Chicken Cordon Bleu for decades and have never fussed with a sauce. A nice flavourful melting style cheese and ham along with the chicken has enough taste for us.
We’ve used the usual Swiss, and several other cheeses such as Fontina, Monterey Jack, and Gruyere…..whatever we happen to have on hand; sliced or silvered. We only count the Carbs in the bread or rice crumbs. About half of the egg and milk mixture will be used, so we don’t include the milk.
*Gluten Free Rice Crumbs are denser than Panko, so there will be more volume (2/3 cup vs 1/3 cup), but we do use about the same amount measured by grams. This is a perfect example where measuring by the gram vs imperial cup makes sense. The Panko package says 30 grams = ½ cup. We measure 30 gr = 1/3 cup, and hence use that calculation for CHO accuracy.
